Modules

? Modules are a way of managing the user environment

? Modules lets users modify the environment on the fly

? New users do not need to do the following steps: ? To enable modules, the user will need to copy the CHPC

bashrc and tcshrc to their home directory:

cp /uufs/chpc.utah.edu/sys/modulefiles/templates/bashrc ~/.bashrc cp /uufs/chpc.utah.edu/sys/modulefiles/templates/tcshrc ~/.tcshrc ? To set up the default CHPC environment, users will also need to copy the

custom.sh and custom.csh scripts cp /uufs/chpc.utah.edu/sys/modulefiles/templates/custom.sh ~/.custom.sh cp /uufs/chpc.utah.edu/sys/modulefiles/templates/custom.csh ~/.custom.csh

? Make sure to save a copy of your old .bashrc/.tcshrc!
